- foundation for a Program Evaluation And Review Technique (PERT)or Critical Path Method (CPM)analysis. It (1) visualizes all of the individual tasks to complete a given job or program; (2) points out interrelationships; and (3) is comprised of arrows linking circles (nodes).
- system used as a complement to multiprogramming, time sharing,and satellite transmission of computer data and programs.Accounting, auditing, and tax practitioners may benefit from the linking of microcomputers through Local Area Network (LAN). LANs allow for data exchange, electronic mail, and pooling of data files.
terminals, computers, and processors connected together by telephone lines or cable for the purpose of approving financial transactions. Among the numerous bank-to-bank networks are, Automated Teller Machine (ATM) networks, which are electronic banking systems comprising numerous bank-owned ATMs, each connected directly or indirectly to a central computer facility called a switch that routes transactions to the appropriate bank for approval and posting to customer accounts. Other examples of banking networks are Automated Clearing House (ACH) networks, electronic point-of-sale (POS) systems, the Federal Reserve's federal wire (fed wire), and the Clearing House Interbank Payments System (CHIPS).
a system where different computers are linked together. A Local Area Network (LAN) links computers in the same or adjacent buildings together. A Wide Area Network (WAN) links computers over a wide area-in some cases worldwide. Networks are valuable because they allow the users to share data, send electronic mail to each other, and share access to hardware devices such as printers.
a set of computers connected together.
- group of affiliated stations interconnected for the simultaneous broadcast of the same programs. A network usually consists of a program-producing central administering organization, owned and operated stations, and independently owned and affiliated stations. The network produces or buys a program that is economically unfeasible for a single station to produce and sells it to national advertisers for an amount equal to program production costs plus the affiliates' air-time charges. With the network system, advertisers reach larger audiences at a lower cost per person than with a single station, and local stations get key programming to attract sponsors. National networks offer complete national coverage of an advertising message. Regional networks concentrate on a specific geographic area, providing a means to cater to regional preferences. Tailor-made networks are a group of stations joining together on a temporary basis for a special program. Cable networks deal with satellite-delivered programming.
- group of noncompeting agencies or executives who meet to exchange information or services and develop contacts; called networking.
- group of newspapers spread over a wide geographic region, whose advertising space is sold as a unit under one billing.
